[php] Amazon S3 Programming

未分類



因為主機有異地備份的需求


所以找了一下相關的資料



















這是一個用 php 寫的 amazon S3 的 class


用法還滿簡單的





$endpoint = 's3-ap-northeast-1.amazonaws.com';
$bucket_name = 'your_bucket_name';
$use_ssl = false;

$s3 = new S3($awsAccessKey, $awsSecretKey, $use_ssl, $endpoint);
s3->putObjectFile($local_filename, $bucket_name, $remote_filename, S3::ACL_PUBLIC_READ);
unset($s3);






以上動作就可以把一個本地的檔案塞到遠端去



$awsAccessKey 跟 $awsSecretKey

是存取 S3 的一對資料 (類似帳號密碼)

有些可以存取S3的 ftp 軟體也會需要這對資料



只要把這個key pair給別人

別人就可以存取你的S3



$bucket_name 是 bucket 的名稱 (廢話)

S3 沒有什麼多層目錄的概念

在你的帳號下 只能建立類似 "籃子" 的容器

然後你可以把檔案都丟在這個籃子裡

所以 $bucket_name 就是寫入你要存取的籃子的名稱



至於籃子 可以先在 S3 用網頁介面開好

也可以用 API 去開

可自行研究 bucket 相關的函數



再來是 endpoint

因為 S3 在世界各地有數個 data center

你可以選擇距離你自己主機近的 data center

不過每個 data center 的費用計算都不一樣

(美國是最便宜的)



如果你是用預設的 data center

則在 建構子的地方不需要指定 endpoint

可以只寫這樣



$s3 = new S3($awsAccessKey, $awsSecretKey);



我是因為好玩 開了一個 tokyo 的 bucket

結果連線的時候就噴了錯誤訊息

(訊息也看不懂)



後來查了一下才發現

原來要指定 bucket 相對的 endpoint

如果你開了一個其他地方的 endpoint

但是在 new 的時候沒有指定

他就會用美國的 endpoint 去操作

然後就會噴錯誤...



endpoint 可以到這個網址查詢



第三個參數是是否要用 SSL

就看有沒有需要



最後就是 putObjectFile 這個 function

主要就是把檔案放上去

指定本地檔案路徑跟檔案名稱 (fullpath)

要放的 bucket, 遠端的檔案名稱, 還有存取權限

就可以了



我的需求是寫虛擬主機幫客戶備份資料的功能

本來想說挑離 VPS 近的 endpoint

但是後來想想

傳輸比較快也沒什麼特別意義

反正傳的完就好了

想想還是用美國的 endpoint 就好了



Amazon S3 的服務算是滿便宜的

他有三種收費項目

一個是容量大小

一個是資料傳輸(只收傳出的流量)

最後一個是存取次數 (一千次以下免費)

而且是用越多越便宜



因為我是備份服務

所以大部分都是放進去

很少拿出來

然後存取次數又少

所以幾乎只有被收容量的費用



另外也有直接把 S3 掛載在本地磁碟的應用方法

我試了好幾個版本 掛載成功

但是 ls 就出現錯誤訊息...

還沒研究出來是什麼問題

不然當做本地端存取

事情應該會簡單很多
